Method of lining metallic walled carriers

ABSTRACT

Method and apparatus for securing liners to metallic walled cargo carriers including an end weldable stud adapted to pass through an aperture in the liner and to be end welded to the metallic wall of the cargo carrier by means of an electric stud end welding technique together with a spring retainer including a thin flange on one end larger than the aperature in the wall panel and spring fingers projecting inwardly and away from the flange and into the aperature of the panel to permit the retainer to fit flush with the outer surface of the wall panel and to grip the stud to secure the wall panel in engagement with the metallic wall of the cargo carrier.

ample and that numerous changes in the details of construction and the combination and arrangement of parts may be restored to without departing from the I claim:

1. The method of lining metallic walled cargo carriers with liner panels comprising the steps of: perforating the panel with holes of diameter in excess of the diameter of the chuck of a stud welding gun at predetermined locations at which it is desired to carrier, positioning the panel in place,

positioning a smooth elongated metallic "stud of length less than the thickness of the panel into the chuck of the stud welding gun and inserting the chuck of the stud welding gun through the perforation to bring the end of the stud into contact with the metallic wall and center the stud within the hole,

welding one end of the stud to the metallic wall by means of the electric stud end welding technique,

positioning a speed nut having an outer flange of diameter larger than the hole and an extended resilient stud engaging portion in engagement with the outer surface of the panel and stud respectively;and

impacting the speed nut with sufficient force .to draw the panel into tensioned engagement with the metallic wall.
